installed when using its features. Added postgres.E005 to validate 'django.contrib.postgres' is in INSTALLED_APPS when using: * PostgreSQL-specific fields (ArrayField, HStoreField, range fields, SearchVectorField), * PostgreSQL indexes (PostgresIndex and all subclasses), and * ExclusionConstraint The check provides immediate feedback during system checks rather than failing later with obscure runtime and database errors.

limit_choices_to.
2021-08-06Fixed #32983 -- Added system check for redundant related_name on symmetrical ↵Nick Touran
